[maxmsp] Re: using waveform display to edit soundbites/samples

Wow, guys.  Thanks for the amazing advice.  I should be able to get this working exactly how I want based on this info, but I'm curious Nick if you could explain how line~ is getting play~ to work this way.  zl sends line~ 4 floats, the first which is clearly the start point, the third the end point, and the fourth the time in milliseconds, but the second number is always 0.  Is that just a place holder of sorts?
Thanks again!
